> After commit e9d8b2c2968499c1f96563e6522c56958d5a1d0d (xen-netback: > disable rogue vif in kthread context), a fatal (protocol) error would > leave the guest Rx thread spinning, wasting CPU time. Commit > ecf08d2dbb96d5a4b4bcc53a39e8d29cc8fef02e (xen-netback: reintroduce > guest Rx stall detection) made this even worse by removing a > cond_resched() from this path. > > Since a fatal error is non-recoverable, just allow the guest Rx thread > to exit. This requires taking additional refs to the task so the > thread exiting early is handled safely. > > Signed-off-by: David Vrabel <david.vra...@citrix.com> > Reported-by: Julien Grall <julien.gr...@linaro.org> > Tested-by: Julien Grall <julien.gr...@linaro.org> Applied, thank you. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
